Abstract

A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.
